摘要
文章采用PT14型扩散硅气体压力传感器测量液体的表面张力系数的新方法,实现了非电量电测,提高了实验的精度和稳定性,并对测量原理、测量误差做了详细的阐述和讨论。结果表明,此法简易可行,有推广价值。
The paper introduced a new way to measure the liquid surface tension coefficient by using silicon gas pressure sensor of type PT14. That new measuring way not only achieved non-capacitance measuring, but also improved the precision and stability of experimentation. The paper also expounded the theorem, measuring error and discussion. The conclusion of it manifestation: this way was not only easy and workable, but also had large value to be pushed ahead.
